7. The DIFFERENCE Consortium DIFFERENCE Appl Advanced IT Milestones DIFFERENCE –Late 1996 - NMF Long Beach meeting –July 1997 - Workshop in Dublin –Aug 1997 and Aug1998 - Review of Fora work –Nov 1997 - DOT Eurescom workshop –Jan 1998 - Deliverable 5 –Sep 1998 - DOT Eurescom workshop –Ongoing - Present to ACTS, NMF,OMG, Eurescom

9. The DIFFERENCE Consortium DIFFERENCE July ‘97 workshop -Some Insights DOT selection based on non-funcal requirements Starting Point will drive selection of DOT to use –Telecoms style starting point (IN, ATM, TMN..) “heritage” important, very important Telecom influences IT! Coexistence and openness key –Internet style starting point (TCP, SNMP, WWW..) which DOT will embrace push technologies, Intelligent Agents, Security Frameworks quickest? DOT Selection will also be driven by –Cost Effectiveness, Openness of Frameworks

11. The DIFFERENCE Consortium DIFFERENCE Strengths/Weaknesses TMN

12. The DIFFERENCE Consortium DIFFERENCE The Strengths of TMN Ref Model Gradually being accepted in some areas Technology up N/W Info models Layering & FCAPS Command/Control archal support Comprehensive abstraction Managed resources Generic Mgmt services Good link to OSI Well defined protocol stacks Support for Sys Architects Support for Sys Designers Support for Sys Implementors

13. The DIFFERENCE Consortium DIFFERENCE The Weaknesses of TMN Business Process support, not top down approach Granularity OSs Neglects General IT support Support for Legacy Heuristics of when to use -LT invest Customer control Lack Peer to Peer Not take account of DOT or IT tools “Neutrality” FCAPS/Business processes ? ADEs not good at Trans, persist etc. Suitability for multiple n/ws or Internet Lack support for simple coop interactions Lack conformance stmts Lack cost effective tools/technologies Lack confidence longevity products, TMN component market Support for Sys Architects Support for Sys Designers Support for Sys Implementors

14. The DIFFERENCE Consortium DIFFERENCE Going forward... Process going forward –consensus on issues –select work items that can be progressed together with Fora application of Advanced IT Strengths/Weaknesses TMN System/Enterprise mgmt of Telecoms Mgmt Neutral Business/Info modelling –Workshops and White papers Fora ACTS

15. The DIFFERENCE Consortium DIFFERENCE Evolution of Telecom Management DIFFERENCE plan to progress work items –July 1998 - initial discussion –Sep 1998 - DOT Eurescom workshop –Sep 1998 - OMG Telecoms DTF meeting –Oct 1998 - ACTS ACM –Oct 1998 - NMF meeting –Nov 1998 - DIFFERENCE Workshop

16. The DIFFERENCE Consortium DIFFERENCE Going forward... together! Mutual benefit to going forward together –How? this workshop consensus building with other fora November workshop follow on an open invitation! –Get involved, follow the work.. –Register at …. –We’ll keep you informed
